Title:
WFI instruction results in unhandled CPU exception
Status in QEMU:
Fix Committed
Bug description:
Hi
I refer to the WFI instruction. The bytecode is 0xe320f003. After the
execution, qemu exit with the following crash log.
qemu: unhandled CPU exception 0x10001 - aborting
R00=00000001 R01=40800b34 R02=40800b3c R03=000102ec
R04=00010a28 R05=00010158 R06=00087460 R07=00010158
R08=00000000 R09=00000000 R10=00085b7c R11=408009f4
R12=40800a08 R13=408009f0 R14=0001057c R15=000102f8
PSR=60000010 -ZC- A usr32
qemu:handle_cpu_signal received signal outside vCPU context @
pc=0x7f5c21d0fa12
WFI aims to enter a low-power state and wait for interrupt. The raised
exception seems not a right behavior. I can provide a testcase if you
needed. Many thanks.
Regards
Muhui
